E05.41 Thyrotoxicosis factitia with thyrotoxic crisis or storm
ICD10CM code
ICD10CM
Name of the Condition
Thyrotoxicosis factitia with thyrotoxic crisis or storm
Also known as Factitious hyperthyroidism; may involve a thyrotoxic crisis or thyroid storm.
Summary
This condition results from the excessive intake of thyroid hormones, leading to severe hyperthyroidism. A thyrotoxic crisis, or thyroid storm, is a life-threatening exacerbation of symptoms requiring urgent medical attention.
Causes
Caused by the intentional or unintentional consumption of excess thyroid hormone medications, often in individuals self-medicating for weight loss or other reasons.
Risk Factors
Use of thyroid hormone supplements without medical supervision.
History of psychiatric conditions or Munchausen syndrome.
Higher occurrence in individuals with access to thyroid medications.
Symptoms
Symptoms include rapid heartbeat, anxiety, unexplained weight loss, heat intolerance, sweating, tremors, and possible heart failure. In a crisis, high fever, delirium, or coma may occur.
Diagnosis
Diagnoses involve blood tests measuring thyroid hormone levels (T3, T4) and TSH, along with a physiological assessment and patient medication history.
Treatment Options
Discontinuation of thyroid hormone intake is critical.
Supportive treatments for a crisis may include beta-blockers for heart rate control, antithyroid medications, and hospitalization for severe cases.
Treatment addresses both symptom management and underlying intake behavior.
Prognosis and Follow-Up
The prognosis improves significantly with prompt treatment and cessation of hormone intake.
Regular follow-up is necessary to monitor hormone levels and adjust treatments, along with psychological support if needed.
Complications
Potential complications include heart failure, osteoporosis, severe weight loss, and mental health issues if untreated.
Lifestyle & Prevention
Avoid unsupervised thyroid hormone consumption.
Educating at-risk populations, particularly those seeking weight loss supplements, is crucial.
When to Seek Professional Help
Immediate medical care is needed for symptoms of a thyrotoxic crisis, such as severe heart palpitations, fever, confusion, or loss of consciousness.

Tips for Medical Coders
Ensure differentiation between exogenous hormone intake versus intrinsic gland overactivity.
Be vigilant for documentation indicating self-administration of thyroid agents leading to crisis situations, to accurately code E05.41.
